Details	To investigate the distribution of Mg in the Hiroshima Regional Urban Area, concentrations of Mg in the environmental elements of aquatic and terrestrial areas were measured. Sediments, benthos, seaweeds, granites, soils, and agricultural farm plants were selected for the measure. Concentrations were determined by the inductively coupled plasma atomic emission spectrometry, visible spectrometry, and colorimetric method. Ulva pertusa contained Mg the highest among the elements examined. Concentrations of Mg in the sediment extracts were as high as those of seaweeds among the aquatic elements, whereas, the Mg of agricultural farm plant extracts were higher than those of soils when compared among the terrestrial elements. The three ways of measurement could visible one aspect of the food environment, in which local residents live, and contribute for the evaluation of ecosystem in the Hiroshima Regional Urban Area.
